IPC: B23K35/362
Filed: 1957-07-02
Abstract: 863,369. Coating with metals. HORWITZ, G. J. July 2, 1957, No. 20917/57. Class 82(2) [Also in Group XXII] In forming a metal coating on a metal surface the metal surface is coated with a mixture containing a compound selected from the group consisting of phosphates, arsenates, antimoniates, antimony oxides and bismuth oxides and a compound of a metal, the metal having a higher melting point than phosphorus, arsenic, antimony or bismuth and the mixture being capable of forming an alloy on reduction, and the mixture is reduced at elevated temperature. The mixture may comprise nickel monoxide, nickel oxide or nickel carbonate and ammonium dihydrogen orthophosphate or diammonium monohydrogen orthophosphate or triammonium orthophosphate mixed with water to a consistency for brushing, dipping or spraying. In an example 2¢, 4 or 8 parts of NiO are mixed with 1 part of ammonium dihydrogen orthophosphate. The coating is reduced in hydrogen or a mixture of nitrogen and hydrogen, possibly after predrying the coating, to reduce the compounds to a nickel-phosporus alloy. The nickel oxide in the mixture may be replaced wholly by copper oxide, chromium oxide or molybdenum oxide or in part by cobalt oxide, copper oxide, tungsten oxide, or iron oxide. Instead of the mentioned ammonium phosphates, mono-ammonium phosphate bismuth oxide, bismuth trioxide, orthoammanium dihydrogen arsenate or orthoammonium monohydrogen arsenate or ammonium arsenate or antimoniate may be used. In an embodiment a flat sheet 1, Fig. 1, is coated with a water suspension of nickel oxide and diammonium phosphate which is then dried and heated at 1600-1900‹F. in hydrogen or a mixture of hydrogen and nitrogen to produce a nickel phosphorus alloy on the sheet. The sheet is then formed into a tube with lapped or butted edges. If the edges are lapped they may be spot or tack welded and reheated to effect brazing. In forming the exhaust pipe of an internal combustion engine the following mixtures may be employed and reduced in hydrogen, a mixture of hydrogen and nitrogen or cracked gas consisting mainly of carbon monoxide, nitrogen and hydrogen: NiO (40%) CuO (30%) (NH 4 ) 2 HPO 4 ) (15%)H 2 O (15%), NiO (60%) WO 3  (10%) (NH 4 ) 2 HPO 4  15%) H 2 O (15%), NiO (60%) CoO (10%) (NH 4 ) 2 HPO 4 (15%) H 2 O (15%). Metal parts are each coated with a mixture and with the coated surfaces in contact the members are heated in a furnace in hydrogen to effect brazing (see Group XXII) The following mixtures may be employed in carrying out the invention: NiO; CoO; (NH 4 ) H 2 PO 4 ; NiO Bi 2 O 3 ; water NiO; Bi 2 O 3  NH 4 OH; CuO, Sb 2 O 3  Cr 2 O 3  HCL, H 3 PO 4 , NiO; CoO (NH 4 )H 2 PO 4 ; NiO; Cr 2 O 3 ; (NH 4 ) H 2 PO 4 . The water in the mixture may be replaced by carbon tetrachloride, methyl alcohol or ethyl alcohol and a wetting agent may be employed in the mixture. It is stated that cast iron, cast steel, molybdenum stainless steel and titanium alloy may be coated or brazed.
